Lithium business net sales increased 39.1% to $68.6 million from $49.3 million.

Gross margin increased to 19.3% of net sales compared to 19.0%.

Net income attributable to the Company increased 21.7% to $6.1 million, or $0.39 per diluted share, compared to $5.0 million, or $0.32 per diluted share. Excluding GZ Highpower, net income attributable to the Company increased 29.4% to $6.1 million from $4.7 million.

Mr. George Pan, Chairman and CEO of Highpower International, commented, "During the third quarter of 2018, we once again achieved net sales growth that surpassed our guidance thanks to healthy growth in both our lithium ion and Ni-MH battery businesses. New and existing customers in the high-end consumer product, industrial application, and artificial intelligence product industries in particular grew our lithium ion battery business. In addition, our Ni-MH battery business benefited from increased demand generated by the trend of consumer electronics providers switching from one-time-use batteries and nickel-cadmium batteries to clean re-chargeable batteries.

"The high price of raw materials in the third quarter declined slightly quarter over quarter. We were also able to improve production efficiency and scale, which helped us maintain our gross margin from the prior year period. At the same time, we are concerned about the uncertain impacts from global trade conflicts in the near future. However, we will spare no effort to execute on our strategy of producing higher quality and safer battery products and services while managing our prices, operations, and customer expectations to minimize the impact," Mr. Pan concluded.

Use of Non-GAAP Measures

The Company has supplemented its reported GAAP (generally accepted accounting principles) financial information with non-GAAP measures. EBITDA was derived by taking earnings before interest expense (net), taxes, depreciation and amortization. The presentation of this additional information is not meant to be considered in isolation or as a substitute for results prepared in accordance with U.S. GAAP. The Company believes this non-GAAP measure is useful to investors as it provides a basis for evaluating the Company's operating results in the ordinary course of its operations. This non-GAAP measure is not based on any comprehensive set of accounting rules or principles. The Company believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with its results of operations as determined in accordance with U.S. GAAP and that these measures should only be used to evaluate the Company's results of operations in conjunction with, and not in lieu of, the corresponding GAAP measures. EBITDA is reconciled in the table below to the most directly comparable measure as reported in accordance with GAAP.
